Mixtures can either be homogeneous or heterogeneous. A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties.A heterogeneous mixture is a type of mixture in which the components can be seen, as there are two or more phases present.One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures.A homogeneous mixture in which there is both a solute and solvent present is also a solution.ir is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.

Why does it glow blue? It's the Cherenkov radiation: 'Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium.' It's going faster than the speed of light (in water).
As we heat a substance, itï¬rst glows a dull red; then a bright red, then orange, yellow,white, and ï¬nally bluish-white. This happens because thedistribution of energy with wavelength shifts topredominantly shorter and shorter wavelengths as thetemperature rises.
